BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a wrapper for rice covered with layerthat is used to wrap a lump of rice covered with layer, and moreparticularly, to a wrapper for rice covered with layer that can beconveniently separated from rice covered with layer at one time.

2. Description of the Related Art

In a conventional wrapper that is used to wrap a lump of rice coveredwith layer, layer is interposed between two layers, that is, inner andouter layers that each have a rectangular shape and are made of aplastic material, and edges of the inner and outer layers are attachedto each other. Meanwhile, a cutting band, which extends in alongitudinal direction, is provided between the inner and outer layersin order to facilitate to the cutting of the wrapper for rice coveredwith layer for the purpose of the eating of rice covered with layer.

In order to eat the rice covered with layer that is wrapped as describedabove, first, a step (i) of cutting the outer layer of the wrapper forrice covered with layer into left and right halves with respect to thelongitudinal direction is performed by pulling a cutting band, which isprovided in the middle of the wrapper for triangular rice covered withlayer in a longitudinal direction, from the top to the bottom in avertical direction on the front side of the wrapper for triangular ricecovered with layer.

After that, if a step (ii) of separating the wrapper into left and righthalves with respect to a centerline is performed by pulling the cutwrapper for rice covered with layer toward both sides, only layer andrice remain. Then, a user wraps the triangular lump of rice with layer,and eats the rice covered with layer.

In order to eat the rice covered with layer that is wrapped as describedabove, a cutting band, which is provided on the outer layer in avertical direction, is pulled from the top to the bottom on the frontside of the triangular rice covered with layer. Then, the cutting bandis pulled from the bottom to the top on the rear side of the triangularrice covered with layer. Accordingly, the outer layer is cut so as to beseparated into left and right halves with respect to a centerline.

Meanwhile, since the inner layer has a slot opened in a verticaldirection at the middle portion thereof, a separate cutting operationdoes not need to be performed. Therefore, the outer layer and the innerlayer of the wrapper are divided into left and right halves portion withrespect to the centerline of the triangular rice covered with layer bypulling the cutting band that is provided on the outer layer. Then, thewrapper can be separated by pulling the wrapper toward the left andright sides.

However, the above-mentioned wrapper where the inner layer is cut isused to wrap triangular rice covered with layer. For this reason, therehave been problems in that it is not possible to allow expiration dateto be lengthened, the taste of the triangular rice covered with layerdeteriorates, and layer is made moist due to vapor generated from rice.

In order to solve the above-mentioned problems, a wrapper has beendisclosed in Korean Patent No. 495321. In the wrapper, as shown in FIG.16, an inner layer 100 does not have a slot, and a cutting band 200 isfurther provided on the inner layer 100 to cut the inner layer 100instead.

Accordingly, according to Korean Patent No. 495321, as shown in FIG. 17,an outer layer 300 is cut by a cutting tape 400 for separating the outerlayer 300, from the top to the bottom in a vertical direction on thefront side of the triangular rice covered with layer. Then, the outerlayer is cut by the cutting tape from the bottom to the top in thevertical direction on the rear side of the triangular rice covered withlayer (see steps (a) to (c) in FIG. 17).

Subsequently, like the outer layer, the inner layer 100 is cut by thecutting band 200 for separating the inner layer 100 in the verticaldirection of the triangular rice covered with layer (see step (d) inFIG. 17). As a result, it is possible to cut the inner and outer layers100 and 300 into left and right halves.

As described above, the cutting tape 400 for separating the outer layer300, and the cutting tape 200 for separating the inner layer 100 areseparately provided in the wrapper disclosed in Korean Patent No.495321. For this reason, in order to completely remove the wrapper, thecutting band 200 for separating the inner layer 100 needs to be grippedagain to cut the inner layer 100 after the cutting of the outer layer300.

Accordingly, as compared to a step of cutting the conventional wrapperfor rice covered with layer, a step (iii) of cutting the inner layershould be performed in addition to a step (i) of cutting the outer layerand a step (ii) of separating the wrapper into left and right halves.Accordingly, there has been a problem in that product competitiveness oftriangular rice covered with layer pursuing convenience deteriorates dueto this inconvenience.

Steps of a procedure for removing the wrapper from the rice covered withlayer, which is wrapped with the wrapper according to the presentinvention, will be described below.

FIG. 10 is a view illustrating a step (a) of cutting the outer layer ofthe wrapper for rice covered with layer, which wraps rice covered withlayer, according to the present invention.

First, a user grips the cutting band 11, which protrudes over the upperend of the outer layer 10.

FIG. 11 is a view illustrating a step (b) of cutting the outer layer ofthe wrapper for rice covered with layer, which wraps rice covered withlayer, according to the present invention.

Then, the user pulls the cutting band 11 in a vertical direction fromthe top to the bottom on the front side of the triangular rice coveredwith layer. Accordingly, the portion of the outer layer 10, whichcorresponds to the front side of the triangular lump of rice, is cut soas to be separated into left and right halves with respect to acenterline.

FIG. 12 is a view illustrating a step (c) of cutting the outer layer ofthe wrapper for rice covered with layer, which wraps rice covered withlayer, according to the present invention.

Finally, if the user continues to pull the cutting band 11 from thebottom to the top on the rear side of the triangular rice covered withlayer through the bottom side of the triangular lump of rice, theportion of the outer layer 10 corresponding to the rear side of thetriangular lump of rice is also cut so as to be separated into left andright halves with respect to a centerline. As a result, the outer layer10 is separated into left and right halves with respect to a centerline.

FIG. 13 is a view illustrating a step (a) of cutting the inner layer ofthe wrapper for rice covered with layer, which wraps rice covered withlayer, according to the present invention.

First, in order to tear the inner layer, a user grips the both sideportions of the outer and inner layers 10 and 20 on the bottom of atriangular layer-and-rice body and pulls the both side portions of thelayers toward the left and right sides.

FIG. 14 is a view illustrating a step (b) of cutting the inner layer ofthe wrapper for rice covered with layer, which wraps rice covered withlayer, according to the present invention.

If the user continues to pull the left and right portions of the outerand inner layers 10 and 20 of the wrapper for rice covered with layer,the second attachment portion 24 of the second half 22 begins to bedetached from the first attachment portion 23 of the first half 21.

In this case, the protruding faces 23 a and 24 a, which are formed atthe first and second attachment portions 23 and 24, have the shapes ofwhich the widths thereof are decreased toward the outer ends of thefirst and second halves 21 and 22 in a transverse direction. For thisreason, if tension is applied to the protruding faces at the beginningto some extent, the protruding faces are separated from each other eventhough a large force is not applied to the protruding faces afterward.As a result, a user can easily separate the inner layer 20.

In this embodiment, a step (ii) of separating the wrapper into left andright halves in the related art and a step of cutting the inner layerare performed at the same time. Accordingly, even though an additionalstep (iii) of cutting the inner layer is not performed, it is possibleto separate the wrapper for rice covered with layer.

FIG. 15 is a view showing that the outer and inner layers of the wrapperfor rice covered with layer according to the present invention are cutfrom each other.

If the user continues to pull the left and right portions of the outerand inner layers 10 and 20 of the wrapper for rice covered with layer,the first and second halves 21 and 22 are completely separated towardthe left and right sides with respect to a centerline, so that onlylayer and rice remain. Then, the user wraps the triangular lump of ricewith layer, and eats the rice covered with layer.

According to the present invention, a slot is not formed at the middleof the inner layer 20 as described above. Therefore, it is possible toallow expiration date to be lengthened, the taste of the rice coveredwith layer does not deteriorate, and layer is made moist due to vaporgenerated from rice. Further, it is possible to easily cut the wrapperfor rice covered with layer by performing only a step (i) of cutting theouter layer and a step (ii) of separating the wrapper.
